SOLUTION: give that (-3,-5)and(-1,-4) are points on the same line find a point-slope form of the equation for this line I know that the slope is 1/2 then i get lost in how to put it in point

You made use of the point-slope formula
What you needed is the GENERAL point-slope formula:
( -3, -5 )
( -1, -4 )

Multiply both sides by

----------------------
check answer:
( -3, -5 )

---------------
( -1, -4 )

OK

The slope of the line is the change in y over the change in x. This is 1/2 as you show.
Point slope formula
y-y1=m(x-x1). m is the slope. Use either point for the x1 or y1. You will get the same result.
y- (-5))=(1/2)(x-(-3))
y+5=(1/2)(x+3)
y+5=(1/2)x+3/2
y=(1/2)x-(7/2)
using the other point
y-(-4))=(1/2)(x-(-1))
y+4=(1/2)(x+1)
y+4=(1/2)x +(1/2)
y=(1/2)x-(7/2)
